Currently the flag that the input data in a user or group lookup request
might be an override value is only set if no cached entry was found. If
the cached entry of an object with overrides is expired and a request
with the override value as input is processed the flag is not set and
the backend might not be able to find the right entry on the server.
Typically this should not happen because of mid-point refreshes. To
reproduce this create a FreeIPA user and override the login name for a
specific view. On a client which has this view applied call
getent passwd overridename
sss_cache -E
getent passwd overridename
The second getent command will still show the right output but in the
logs a
[sss_dp_get_reply] (0x1000): Got reply from Data Provider - DP error
code: 3 errno: 0 error message: Account info lookup failed
message can be found for the second request.

To allow IPA clients to offer special attributes of AD users form
trusted domain the extdom plugin on the IPA server must send them to the

attributes given by the NSS/IFP user_attributes option to the list of
attributes returned by sss_nss_getorigbyname().

About case_sensitive=preserving and services.
The name of the service can be preserved in
result of 'getent service'. However we
should still lowercase the protocol and
service aliases because they serve as keys
in some queries to sysdb. The lowercasing is done
by the provider already. If we did not do that,
we would lose case insesnsitivity.
With this patch the responder preserves the
case of service name and protocol, to match
the case that is stored in the sysdb (however
the protocol is already lowercased by provider,
so it was done only for consistent use of the
case_sensitive=preserve option in the responders
and only the case of name is the same as in
ldap).

This patch adds a new request to the nss responder which follows the
same flow as a SSS_NSSGETSIDBYNAME request but returns more data than
just the SID. The data is returned as pairs of \0-terminated strings
where the first string is the sysdb attribute name and the second the
corresponding value.
The main use case is on the FreeIPA server to make additional user and
group data available to the extdom plugin which then send this data to
SSSD running on FreeIPA clients.

Since we cannot know if a SID belongs to a user or a group a lookup
should only fail if the given name is in both the negative cache for the
users and the groups.
Currently if the SID for a group called 'abc' should be looked up and
the negative cache for the users contain an entry for 'abc' the request
fails.

If we query group from subdomain it can contain users from different domains.
All members from subdomain have fully qualified name, but member from main
domain aren't. In function fill_members, we extracted name and domain with
function fill_members. Later, we called function sss_fqname the first time
with queried group domain and the second time with parsed domain.
It caused following error in nss responder:
[fill_members] (0x0040): Failed to generate a fully qualified name for member
[user2_dom1@sssdad_tree.com] of group [group2_dom2@sssdad_tree.com]! Skipping
The test test_nss_getgrnam_mix_dom_fqdn passed, because name of main domain
and name of subdomain had the same length, Therefore there was not problem
in function fill_members with calling sss_fqname with different domains.
This patch also changes name of subdomain to prevent such problems in future.

With this patch the NSS and PAM responders can handle user principal
names besides the fully qualified user names.
User principal names are build from a user name and a domain suffix
separated by an '@' sign. But the domain suffix does not necessarily has
to be the same as the configured domain name in sssd.conf of the
dynamically discovered DNS domain name of a domain. The typical use case
is an Active Directory forest with lots of different domains. To not
force the users to remember the name of the individual domain they
belong to the AD administrator can set a common domain suffix for all
users from all domains in the forest. This is typically the domain name
used for emails to make it even more easy to the users to remember it.
Since SSSD splits name and domain part at the '@' sign and the common
domain suffix might not be resolvable by DNS or the given user is not a
member of that domain (e.g. in the case where the forest root is used as
common domain suffix) SSSD might fail to look up the user.
With this patch the NSS and PAM responder will do an extra lookup for a
UPN if the domain part of the given name is not known or the user was
not found and the login name contained the '@' sign.
